Discover the new concealed Piedmontese shutter catch. Invisible design, adjustable clutch, and safe operation from the inside, ideal for walls with external thermal insulation.

At Punto Persiane, innovation is never just an exercise in style; it is an engineered response to the real-world challenges you face on the job. Our goal is never to settle for the standard, but to continuously push boundaries to redefine it.

With this specific vision in mind, we have re-engineered our sash locking system, creating a tool that eliminates compromises during installation. Starting today, September 1st, 2026, the new generation of the concealed Piedmontese shutter catch is officially available to order: the ultimate solution for thick walls and facades with external thermal insulation cladding.

High-Level Safety and Clean Aesthetics

The Piedmontese shutter catch was born out of a specific structural need: to allow the shutter to be locked in the open position without forcing the user to lean out the window. This feature makes it an essential ally for upper-floor installations or for users with limited mobility.

Our new system elevates this concept, combining mechanical efficiency with flawless aesthetics.

  • Concealed design: the body of the catch is fully recessed into the bottom rail or horizontal mid-rail of the shutter. The hardware is completely hidden from view, ensuring a clean facade free of external visual clutter.
  • Controlled dampening: the hardware comes with an included dampening buffer (packaged in the box), designed to ensure that opening and closing are always smooth, controlled, and silent, preventing the sash from slamming.

Technical Evolution: Mechanical Stability and Simplified Installation

To master the complexities of modern projects, we have overcome the limitations of traditional systems by introducing three fundamental engineering upgrades:

  1. Fully non-handed system: we have eliminated the distinction between left and right configurations. The new retainer is universal, drastically simplifying inventory management and installation operations.
  2. New adjustable mechanical friction clutch: we have moved away from traditional and restrictive fixed-spring systems. The new model integrates an advanced mechanical clutch, easily calibrated on-site using a standard Allen key (following the provided instructions). This adjustment allows the installer to set the holding force and the end stop with absolute precision, completely eliminating sash rattling, even in windy conditions.
  3. Tension adjustment and ready to use: the system is delivered fully assembled and ready for calibration. By simply adjusting a single screw, you can modify the tension and the arm projection, adapting it perfectly to any clearance from the wall or master frame.

Compatibility and Ordering

The new concealed Piedmontese shutter catch is designed to offer maximum versatility, integrating effortlessly into your premium projects.

It can be face-fixed (wall-mounted) or frame-mounted on all frames and models within the Calipso and Infinita collections (with the exception of the Oscura and Aida models, and projecting shutter configurations).

Engineering excellence is ready to be integrated into your jobs. You can configure and order the new shutter catch starting today, directly on our Sherpa portal, or by contacting your Punto Persiane sales representative.

What exactly is a Piedmontese shutter catch?
A shutter catch is an essential hardware component used to keep the sash locked in the open position, preventing it from slamming or closing suddenly. The Punto Persiane Piedmontese variant stands out for its engineering: it allows you to lock and release the shutter while remaining comfortably inside the building. It is the premier choice for ensuring safety, especially on upper floors or for users with limited mobility.
Installing external thermal insulation cladding significantly increases wall thickness. With traditional external holdbacks, this added thickness forces users to lean out dangerously to reach the sash. Our Piedmontese catch eliminates this issue: because it is integrated directly into the shutter structure and operated from the inside, it solves one of the most complex installation challenges on modern job sites.
It means refusing to compromise on the aesthetics of the facade. Traditional retaining systems are often bulky and visible from the outside. With our system, the body of the catch is literally “concealed” – fully recessed into the bottom rail or mid-rail of the shutter. The result is a clean, sharp design that remains invisible from the outside, elevating the architectural value of the fenestration system.
The system has been re-engineered to offer maximum versatility and is now completely non-handed, eliminating the distinction between left and right. You can install it on all frames and models within our Calipso and Infinita collections (both wall-mounted and frame-mounted). The only exceptions, due to structural reasons, are the Oscura and Aida models, and projecting shutter configurations.
